In this third book of the Books of Magic (based on the popular comic books of the same name), Timothy Hunter begins to deal with the things he learned about his father in the previous book.
But most of the book concerns the survivors of the Children's Crusade. Of an original 50,000 children, only 800 survived the journey to be sold into slavery. Some of those survivors managed to flee to a magic land where all their dreams and desires were answered.
Now one of those children has come to our world in order to convince Timothy to come and help them. Other powerful children from other worlds have already been brought there. Upon arrival, Timothy discovers that all is not well in paradise. There are squabbles and some things don't work they way they used to.
Eventually the real plot is revealed and Timothy triumphs without actually doing anything (he literally just stood there). As a result, Timothy has found that through bumbling he has managed to now save two worlds; this one and Faerie.
This book is a fast read (short with large type) but it just doesn't seem to work as well as it should. After three mediocre books I just don't think this series is going to take off (and I love the comics).
